Privacy Policy

LinkGuard checks links on your device. This page explains what it processes, what it sends, and what it stores.

Effective date: 2026-10-15

What is processed on your device

• It reads link addresses and link text on supported sites (webmail and web messengers) and, if you turn it on, on all sites.
• What it reads is used only to compare against the comparison list, and is processed on this device.
• Email text, messages, and page content are not sent off your device.

What is sent off your device

The only outgoing request is a domain registration lookup (RDAP), used to get a domain's registration date and registrar.

• Sent: the registrable domain name of a link (for example, example.com)
• Sent to: rdap.org and the RDAP servers of domain registries
• Not sent: path, query, page content, email text, or any information that identifies you
• As with any internet request, an RDAP server can see the IP address the request came from. LinkGuard does not run these servers and does not receive that information.
• If you turn off "Domain registration lookup (RDAP)" in the toolbar popup, this request is not sent either.

What is stored

The items below are kept only in the browser's chrome.storage.local and are not sent to the developer's servers.

• Settings: per-site on/off and RDAP lookup on/off
• RDAP lookup cache: domain, registration date, registrar. Kept for 7 days, then looked up again.

Per-tab counts shown in the popup are held briefly in session storage (chrome.storage.session) and disappear when the browser session ends.

Uninstalling the extension deletes the stored data.

What it does not do

• No analytics or usage tracking.
• No ads.
• No sale of data and no sharing with third parties. The servers that receive the RDAP lookup are the only outside recipients.
• No download or execution of remote code.

Check on all sites

Off by default. Only if you turn it on in the popup and allow the browser's permission request, LinkGuard checks links on all sites in the same way, on your device. You can turn it off at any time.

Changes to this policy

If this page changes, the effective date is updated.
